Subject: libcamera: pipeline: Pass libcamera controls into
pipeline_handler::start()
Applications now have the ability to pass in controls that need to be
applied on startup, rather than doing it through Request where there might
be some frames of delay in getting the controls applied.
This commit adds the ability to pass in a set of libcamera controls into
the pipeline handlers through the pipeline_handler::start() method. These
controls are provided by the application through the camera::start()
public API.
